The speed of a particle is the instantaneous rate at which its distance of travel
is changing.
Over any finite period of time, its speed is:
(distance traveled) / (time to travel the distance).
The direction of travel is irrelevant to a description of speed.
Answer:
it is 59 degrees Fahrenheit
Answer:
(A) As it moves farther and farther from Q, its speed will keep increasing.
Explanation:
When a positive charge Q is fixed on a horizontal frictionless tabletop and a second charge q is released near to it then according to the Coulombs law the force acting on it decreases with the square of the distance between them.
Mathematically:

where:
r = distance between the charges
permittivity of free space
By the Newtons' second law of motion if the we know that the acceleration is directly proportional to the force applied. So as the distance between the charges increases the its acceleration also decreases therefore now the charge feels less acceleration but still continues to accelerate with a fading magnitude.
10^9 giga, 10^6 mega, 10^3 kilo, 10^-3 milli, 10^-6 micro, 10^-9 nano, 10^-12 pico
Potentially they might want centi which is 10^-2
GPE= weight•height= 15 N• 0.22meter= 3.3 Joules
